Also I tried with changing product id.
This is the correct thing to do. The product code must always be changed for a major upgrade. In this case, I'm getting two instances in 'Add/Remove Programs'. The old product has not been removed because you have erroneously set the OnlyDetect attribute to 'yes' on the 'PREVIOUSVERSIONSINSTALLED' UpgradeVersion element. <UpgradeVersion OnlyDetect='yes' Property='PREVIOUSVERSIONSINSTALLED' Minimum='1.0.0.0' IncludeMinimum='yes' Maximum='1.0.1.1' IncludeMaximum='no'/> -- View this message in context: http://n2.nabble.com/Wix-Installer-Upgrade-problem-tp2627135p2629519.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
